The density of carbon dioxide is equal to 1.965 kg `m^(-3)` at 273 K and 1 atm pressure. Calculate the molar mass of `CO_(2)`.

Explanation

The density of `CO_2` at 273K and 1atm pressure `=1.965 kgm^(-3)`
Molar mass of `CO_(2)=?`
At 273 K and 1atm pressure , 1 mole of `CO_2` occupies a volume of 22.4 L
Mass of 1 mole of `CO_2`
`= (1.965Kg)/(1m^3)xx22.4L`
`=(1.965xx 10^3 g xx 22.4xx10^-3 cancel(m^3))/(1cancel(m^3))`
`= 44.01 g`
Molar mass of `CO_2=44 "g mol"^(-1)`.
